Question

if A=B*C .is A perpendicular to the plane containing B*C or is it perpendicular to vector A*B.pls explain

Answer 1

Answer:

Given

A=B*C

A is perpendicular to B*C

OR perpendicular to A*B

according to me if it is perpendicular to the plane of b and c

then cross product of b and c will give a perpendicular to plane b and c

Then this vector will be parallel to a

then the cross product of two parallel is 0 vector

then a×(b×c)=0
